Description

This test case tests the basic functionality of tuned tool. This tool can statically and dynamically tune your system according to selected profile.

Start tuned (via systemd):
```
# systemctl start tuned.service
```
List all available profiles:
```
# tuned-adm list
```
Try to switch between profiles, e.g. for powersave profile:
```
# tuned-adm profile powersave
```
Check if the profile was really set by:
```
# tuned-adm active
```
Try several other profiles.
Try to generate tuned profile from powertop's suggestions:
```
# powetop2tuned test-profile
```
In this generated profile all powertop's tunings are initially disabled, you can selectively enable them by editing /etc/tuned/test-profile/script.sh.
Try to switch to generated profile:
```
# tuned-adm profile test-profile
```
Switch back to balanced profile:
```
# tuned-adm profile balanced
```
Remove generated profile:
```
# rm -rf /etc/tuned/test-profile
```
When done switch tuned completely off by:
```
# systemctl stop tuned.service
```
Check if the tuned process is not left running by:
```
# pgrep tuned
```
